1. If everyone stopped having kids for 10 years, how many people would there be in 10 years? (Because the question is kind of vague, let me assume the following)

a. Everyone currently pregnant would still give birth but procreation would cease entirely
b. The statistical rate of successful births and deaths by natural causes would stay the same (ignoring the Donald Element…)

So taking the current world population of 7,649,888,013 With a global rate of 360,000 births per day meaning that for the next 9 months this number would stay constant until dropping to 0 on June 1st, 2019, and 151,6000 deaths per day, we can crunch the numbers on this one…

There are 260 days between today and June 1st, 9 months from now and when the last currently pregnant woman would give birth. So at 360k/day births, that would mean 93.6M babies would be born and at 151k/day deaths, 39.26M people would croak.

The population that day, when the last baby is born, would be 7,704,228,013 people. Then from June 1st 2019 to September 14th 2028, there are 3,393 days in total. Now we just need to use the death rate of 151k/day, which equates to 512,343,000 buckets kicked in the following 9 years 3 months.

Thus putting our population on September 14th, 2028 at…. 7,191,885,013 people alive world wide! I personally loved the movie Children of Men, and if you haven’t seen it I would definitely recommend checking it out. In the spirit of that, well, rather dower film. If the death rate kept steady at 151k people daily, then it would take 47628 days (and change) for everyone to die if we stopped procreating. Thats roughly 130 and a half years from now. Meaning that on February 7th, 2149 at around [9:00] AM the last human alive would be dead.
